  • a reversing (switchback reversing) gear incorporated in a sheet processor for conveying and processing postal matters, etc. and for reversing the conveying direction of sheets conveyed.
  • the sheet length referred to here is the length of sheets in the conveying direction. Further, the conveying gap between sheets is a distance from the rear end of a sheet to the front end of a sheet that is next conveyed, and is also applicable in the following explanation.

  • the length of the sheet 1 protruding from the reversing roller 11 and the pinch roller 12 is shown when a conveying control parameter that is constant regardless of the length of the sheet 1 was used for the sheet in an optional length.
  • FIG. 1A shows that a protruding length of a sheet 1 that is suited to a detecting is L when the length of the sheet 1 is most short.
  • a protruding length L1 becomes longer than L because the length of the sheet 1 is longer than the length of a sheet 1 shown in FIG. 1A .

  • the longer the length of a sheet 1 becomes the longer the protruding length becomes and comes close to the switching gate provided adjacent to the upper stream side in the conveying direction. Further, the sheet 1 also becomes close to the conveying path in the reversing direction and it becomes difficult to control the turning of the switching gate.
  • the tolerance of variance in protruding amount of a sheet from the entrance of the reversing portion is subject to the installed position or the swing shape of the switching gate and becomes a narrow range.
